South Korea and China agreed on Thursday to prepare for a visit to South Korea by Chinese President Xi Jinping and to cooperate on stalled talks on North Korea’s nuclear programme and on tackling the novel coronavirus. China’s top diplomat, Wang Yi, arrived in the South Korean capital late on Wednesday, after a two-day visit to Japan, as Asian governments prepare for change under a new U.S. administration. “Both sides agreed to actively communicate so that the COVID-19 situation stabilises and conditions are created for President Xi’s visit,” the South Korean foreign ministry said in a statement after Wang held talks with South Korea’s foreign minister, Kang Kyung-wha. China and U.S. ally South Korea have traditionally been suspicious of each other but in recent years they have found common ground in economic cooperation and a shared concern about North Korea’s rush to develop nuclear weapons. “Bilateral ties are showing their strength and ever more vigour.” South Korea’s President Moon Jae-in met Wang separately and they discussed peace on the peninsula, Moon’s office said. U.S. President Donald Trump raised hopes for progress in pressing North Korea to give up its weapons programmes in exchange for the lifting of sanctions but talks with North Korean leader Kim Jong Un stalled. Kang raised the issue of the incoming U.S. administration in her talks with Wang, who expressed “hopes” for its North Korea policy, a South Korean official who declined to be identified told reporters. Wang reiterated China’s opposition to a U.S. missile defence system installed in South Korea in 2017, the official said. South Korea and the United States say the system is designed to counter North Korean missile threats but China fears it undercuts its security interests.
